Ocean Monitoring Instruments With The Anti-pollution Technology

Biofouling problems of ocean monitoring instrumentation were reviewed. The effects of different antifouling material were studied. Three main parts of the study were,(1) To compare different types of material and their effects of antifouling agents, eight of the most common antifouling coatings(self-polishing antifouling coating, biocide-leach antifouling coating, novel environmental antifouling coating, low-surface-energy antifouling coating), copper alloys, antibacterial ceramic, and other self-designed antifouling materials (transparent antifouling coating and antifouling ring) were used. Model components are also used as the equivalents of marine monitor instruments. Form the results, it is shown that the self-polishing antifouling coatings, low-surface-energy antifouling coating, and copper alloys are better at preventing against biofouling.(2) The antifouling capacities of novel zinc acrylate resin, cuprum acrylate resin, acrylate resin with capsaicin structure and antifouling coatings made with those resins have been studied by using raft exposure tests. It was concluded that zinc acrylate resin and cuprum acrylate resin were the most effective.(3) Three derivatives of isothiazolone, capsaicin, and gramine were used as antifoulants in coating formulations. It was shown that the derivatives of isothiazolone and gramine can effectively inhibit biofilming and algal adherence. It was also shown that the effectiveness of the antifouling agent can be extended when a sustained-releasing agent is added to the mixture.
